Do any of the 3.x series of nessus scanners provide for speed control
of the port scan portion of the scan? I am aware of the X machines at
a time, Y checks at a time, but last I had checked, that did not
control the nessus tcp scanner speed.

With Nessus3, you can limit the number of parallel TCP sessions. Apart
from this, nothing changed for nessus_tcp_scanner between Nessus2 and
Nessus3.
The maximum parallelism is mainly computed from max_checks (what you
called "Y"). safe_checks reduces it.
max_checks is clamped down to 5 for this computation.

Note that the maximum parallelism is only reached when you scan a
firewalled machine.
